Answer:
The probability that of the 3 households randomly selected at least 1 owns a sports car is 0.1956.
Step-by-step explanation:
Let <em>X</em> = number of household owns a sports car.
The probability of <em>X</em> is, P (X) = p = 0.07.
Then the random variable <em>X</em> follows a Binomial distribution with <em>n</em> = 3 and <em>p</em> = 0.07.
The probability function of a binomial distribution is:
![P(X=x) = {n\choose x}p^{x}[1-p]^{n-x}\\](https://tex.z-dn.net/?f=P%28X%3Dx%29%20%3D%20%7Bn%5Cchoose%20x%7Dp%5E%7Bx%7D%5B1-p%5D%5E%7Bn-x%7D%5C%5C)
Compute the probability that of the 3 households randomly selected at least 1 owns a sports car:
Thus, the probability that of the 3 households randomly selected at least 1 owns a sports car is 0.1956.
Everywhere you see z, replace the letter with 18.
z/[(3- 2z)] + 4(z - 8)
18/[(3 - 2(18))] + 4(18 - 8)
You finish.
Answer:
Yes the cube will fit.
Step-by-step explanation:
If we don't take into account of how wide of long the cube is and just focus on the height, the edge of a cube with a volume of 9 feet is roughly 2.08 feet. That totals to less than 27 inches, therefore the cube will fit on the shelf.
Answer:
16 square units
Step-by-step explanation:
→ Find the area of the whole triangle
0.5 × ( 5 + 4 ) × 8 = 36
→ Find the area of the small triangle
0.5 × 5 × 8 = 20
→ Minus the area's of the triangles
36 - 20 = 16 square units
